Maren Morris and Alicia Keys Perform ‘Once’ at the 2017 Grammy Awards

Maren Morris won her first Grammys trophy at the 2017 Grammy Awards, and her night got even better when she teamed up with Alicia Keys, a 15-time Grammy Awards winner, to perform "Once."

With giant chandeliers hanging from the ceiling, Morris kicked off the performance wearing a glittering black leotard and cape. She began the song solo, and soon, Keys joined her. Keeping up with Keys is no small feat, but Morris matched her note for note as they sang solo and harmonized flawlessly.

Morris was ecstatic about making her Grammys stage debut; when the performance was announced, the singer tweeted, "Can’t believe I’m saying this, but I’m performing at the #Grammys!!! AND I’m gonna collab with my girl @aliciakeys again for this incredibly special night of music.” The pair collaborated together on CMT’s Crossroads, which aired in December; on that show, they performed hits including Morris' "My Church" and Keys' "If I Ain't Got You."

"Once" is from Morris' debut record, Hero. Though she's a newcomer to country music, she's already made a big impact -- after all, she just won a trophy for Best Country Solo Performance.
